I will agree with lots of the above post - I would personally recommend getting rid of both sharks as one will become too aggressive eventually and could start up with other fish. I would also look to get rid of the barbs - forum members usually recommend a barb only tank due to their aggression (unless it's cherry barbs) and I agree to increase the skirts.
